2711-B5A16

The 2711-B5A16 is a Human Machine Interface (HMI) that is part of Allen-Bradley’s Panelview Standard operator terminal product family. It is specifically part of the PanelView 550 sub-category, featuring a 5.5-inch monochrome screen with a resolution of 256 x 128 pixels and a display area of 120 x 60 mm or 4.75 x 2.38 in. This operator terminal is also equipped with a touch-sensitive screen and a keypad assembly which functions as operator input interfaces. These input interfaces are simultaneously active and provide redundant means of interacting with the connected machine or process. This operator terminal actively communicates with part programmable logic Controllers (PLC) such as Allen-Bradley’s PLC, SLC, and Logix controller series. It may also be used as an HMI device for other compatible controllers and intelligent devices. Communication is accomplished through the integrated communication interface particularly the RS232 interface that supports the DF1 protocol. Another RS232 port is provided which is intended for printer communication. The 2711-B5A16 comes with integrated memory amounting to 240K bytes (application screens) for series E of later and 112K bytes for terminals before series E. This operator terminal is powered by an external supply voltage of 85-264 VAC, 47-63 Hz with a rated power consumption of 20 Watts of 69 BTU/Hr. It has an operating temperature requirement of 85-264 VAC, 47-63 Hz, and storage temperature of -20…70 ° C (-4…158 ° F).

The Allen-Bradley 2711-B5A16 is an obsolete operator terminal in the PanelView 550 series of Human Machine Interface or HMIs. The 2711-B5A16 interfaces with and controls other machines with its LCD, touchscreen, keypad, and communication ports. The LCD has blue monochrome graphics with 256 x 128 pixels of resolution. The touchscreen and keypad make entering data and machine commands easy. The communication ports that the 2711-B5A16 comes with are an RS-232 Printer and Download Communication Port and an RS-232 (DF1) Communication Port, which uses the Allen-Bradley 2711-NC13 cables. The 2711-B5A16 has HMI support for all Allen-Bradley programmable controllers regardless of the series they come in. The Allen-Bradley 2711-B5A16 HMI terminal comes in Series A, B, C, D, E, F, G, and H. The 2711-B5A16 HMI terminal is certified for operation in Class I Zone 2, Class I Division 2, Class II Division 2, and in Class III Division 1 industrial environments. It is protected by a NEMA Type 12, 13, or 4X enclosure, but it is only meant for indoor operation. The 2711-B5A16 is certified for operation in several countries by the CE, CUL, and UL standards. The dimensions of the 2711-B5A16 are 14 x 11 x 8 inches, the dimensions of its keypad are 7 x 10 x 4 inches, and the dimensions of its touchscreen are 6 x 7 x 3 inches. It can support a stainless steel bezel, an antiglare shield for the screen, and an ATA PC memory card. Other convenient features include screen security settings, a real-time clock, alarm functionality, and support for floating point files.
